If between the date of this Agreement and the Effective Time the outstanding shares of Company Common Stock shall have been changed into a different number of shares or a different class, solely by reason of any stock dividend, reclassification, recapitalization, split, reverse split, combination, exchange or readjustment of shares or any stock dividend or stock distribution with a record date during such period or any other similar transaction, the Merger Consideration shall be correspondingly adjusted to reflect such change and to provide to the holders of Company Common Stock the same economic effect as contemplated by this Agreement prior to such action.

Section 3.2 Exchange of Certificates.

(a) Paying Agent. At the Closing, Parent shall deposit, or shall cause to be deposited, with a bank or trust company designated by Parent, the identity and the terms of engagement of which shall be reasonably satisfactory to the Company (the "Paying Agent"), for the benefit of the holders of shares of Company Common Stock, for exchange in accordance with this ARTICLE III, through the Paying Agent, cash in U.S. dollars in an amount sufficient to pay the aggregate amount of the Merger Consideration payable in connection with the Merger pursuant to Section 3.1 in exchange for outstanding shares of Company Common Stock. The funds deposited with the Paying Agent pursuant to this Section 3.2 are referred to as the "Exchange Fund." The Paying Agent shall deliver the Merger Consideration contemplated to be paid pursuant to Section 3.1 out of the Exchange Fund. The Paying Agent shall invest any cash included in the Exchange Fund as directed by Parent; provided that (i) no such investment shall relieve Parent or the Paying Agent from making the payments required by this ARTICLE III, (ii) no such investment shall have maturities that could prevent or delay payments to be made pursuant to this Agreement, and (iii) such investments shall be in short-term obligations of the United States of America with maturities of no more than thirty (30) days or guaranteed by the United States of America and backed by the full faith and credit of the United States of America. In the event the Exchange Fund shall be insufficient to make the payments contemplated by Section 3.1(a), Parent shall promptly deposit, or cause to be deposited, additional funds with the Paying Agent in an amount which is equal to the deficiency in the amount required to make such payment. Parent shall cause the Exchange Fund to be applied promptly to making the payments pursuant to Section 3.1(a). The Exchange Fund shall not be used for any purpose other than to fund payments pursuant to Section 3.1, except as expressly provided for in this Agreement.

(b) Exchange Procedures. Promptly following the Effective Time (but in no event later than five (5) Business Days following the Effective Time), Parent shall instruct the Paying Agent to mail

to each holder of record of a Certificate or Certificates which immediately prior to the Effective Time represented outstanding shares of Company Common Stock (the "Certificates," it being understood that any references herein to "Certificates" shall be deemed to include references to book-entry account statements relating to the ownership of shares of Company Common Stock) and whose shares of Company Common Stock have been converted into the right to receive Merger Consideration pursuant to Section 3.1 (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates (or affidavits of loss in lieu thereof) to the Paying Agent) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration, in each case, in customary form and with such other provisions as the Company and Parent may reasonably agree. Upon surrender of a Certificate for cancellation (or affidavits of loss in lieu thereof) to the Paying Agent together with such letter of transmittal, properly completed and duly executed, and such other documents as may be reasonably required pursuant to such instructions (or, if such shares are held in book-entry or other uncertificated form, upon the entry through a book-entry transfer agent of the surrender of such shares on a book-entry account statement), the holder of such Certificate shall be entitled to receive in exchange therefor the Merger Consideration, subject to deduction for any required withholding Tax, which such holder has the right to receive in respect of the shares of Company Common Stock formerly represented by such Certificate, to be mailed, made available for collection by hand or delivered by wire transfer, as elected by the surrendering holder, within five (5) Business Days following the later to occur of (i) the Effective Time or (ii) the Paying Agent's receipt of such Certificate (or affidavit of loss in lieu thereof), and the Certificate so surrendered shall forthwith be cancelled. No interest will be paid or accrued on any Merger Consideration payable to holders of Certificates. The Paying Agent shall accept such Certificates (or affidavits of loss in lieu thereof) upon compliance with such reasonable terms and conditions as the Paying Agent may impose to effect an orderly exchange thereof in accordance with normal exchange practices. In the event that the Merger Consideration is to be paid to a Person other than the Person in whose name any certificate is issued, the Merger Consideration may be issued to such other Person if the Certificate representing such shares of Company Common Stock is presented to the Paying Agent, accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer or other Taxes have been paid. Until surrendered as contemplated by this Section 3.2, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration or, subject to compliance with Section 262 of the DGCL, the right to demand to be paid the "fair value" of the shares represented thereby as contemplated by Section 3.3.

(c) Further Rights in Company Common Stock. All Merger Consideration paid in accordance with the terms hereof shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of Company Common Stock.

(d) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of Company Common Stock for twelve (12) months after the Effective Time shall be delivered to the Surviving Corporation upon demand, and any holders of Company Common Stock who have not theretofore complied with this ARTICLE III shall thereafter look only to the Surviving Corporation as the general creditor therefor for payment of their claims for the Merger Consideration, without any interest thereon.

(e) No Liability. None of Parent, Merger Sub, the Company or the Surviving Corporation shall be liable to any holder of shares of Company Common Stock for any cash from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If any share of Company Common Stock shall not have been surrendered or transferred immediately prior to the date on which any Merger Consideration in respect thereof

would otherwise escheat to or become the property of any Governmental Entity, any such Merger Consideration in respect of such share of Company Common Stock shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation, and any holder of such share of Company Common Stock who has not theretofore complied with this ARTICLE III with respect thereto shall thereafter look only to the Surviving Corporation for payment of such holder's claim for Merger Consideration in respect thereof.

(f) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if reasonably required by Parent, the posting by such Person of a bond, in such reasonable and customary amount as Parent may direct, as indemnity against any claim that may be made against it with respect to such lost, stolen or destroyed Certificate, the Paying Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration without any interest thereon.

(g) No Further Dividends. No dividends or other distributions with respect to capital stock of the Surviving Corporation with a record date on or after the Effective Time shall be paid to the holder of any unsurrendered Certificates.

(h) Withholding. Parent, the Company, the Surviving Corporation or the Paying Agent shall be entitled to deduct and withhold or cause to be deducted and withheld from the amounts otherwise payable pursuant to this Agreement, including Section 3.5, such amounts as Parent, the Company, the Surviving Corporation or the Paying Agent are required to deduct and withhold under the Code, or any provision of state, local or foreign Tax Law, with respect to the making of such payment. To the extent that amounts are so deducted or withheld, such deducted or withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of whom such deduction and withholding was made. For the avoidance of doubt, Parent, the Company, the Surviving Corporation and the Paying Agent shall be entitled to deduct and withhold taxes pursuant to Section 1445 of the Code unless the Company shall have delivered to Parent and Merger Sub a Certification by the Company that meets the requirements of Treasury Regulation 1.897-2(h)(1)(i).

Section 3.3 Dissenters' Rights. Notwithstanding Section 3.1(a), to the extent that holders of Company Common Stock are entitled to appraisal rights under Section 262 of the DGCL, shares of Company Common Stock issued and outstanding immediately prior to the Effective Time and held by a holder who has properly exercised and perfected his or her demand for appraisal rights under Section 262 of the DGCL (the "Dissenting Shares"), shall not be converted into the right to receive the Merger Consideration, but the holders of such Dissenting Shares shall be entitled to receive such consideration as shall be determined pursuant to Section 262 of the DGCL; provided, however, that if any such holder shall have failed to perfect or shall have effectively withdrawn or lost his or her right to appraisal and payment under the DGCL, such holder's shares of Company Common Stock shall thereupon be deemed to have been converted as of the Effective Time into the right to receive the Merger Consideration, without any interest thereon, and such shares shall not be deemed to be Dissenting Shares. Any payments required to be made with respect to the Dissenting Shares shall be made by Parent (and not the Company or Merger Sub). The Company will give Parent (i) prompt written notice of any demand for appraisal of any shares of Company Common Stock, any withdrawals of such demands, and any other communications received by the Company in respect of the demand, withdrawal, or perfection of appraisal rights and (ii) the opportunity to conduct jointly all negotiations and proceedings with respect to such demands for appraisal of any shares of Company Common Stock under the DGCL. The Company will not, except with the prior written consent of Parent, voluntarily make any payment with respect to any Dissenting Shares or settle or offer to settle any such demands.

Section 3.4 Stock Transfer Books. After the Effective Time, the stock transfer books of the Company shall be closed and thereafter, there shall be no further registration of transfers of shares of Company Common Stock theretofore outstanding on the records of the Company. From and after the Effective Time, the holders of Certificates shall cease to have any rights with respect to such shares of Company Common Stock except as otherwise provided herein or by Law. If Certificates are presented to the Surviving Corporation for transfer following the Effective Time, they shall be canceled against delivery of the applicable Merger Consideration, as provided for in Section 3.1(a), for each share of Company Common Stock formerly represented by such Certificates.

Section 3.5 Company Options, Company Restricted Stock, Company Performance Share Units and Company Phantom Share Awards.

(a) Company Action. Prior to the Effective Time, the Company shall take such actions (including through an action of the Company Board or a duly authorized committee thereof) as are required to give effect to the treatment of the Company Options, Company Restricted Stock, Company Performance Share Units and Company Phantom Share Awards as contemplated by this Section 3.5.

(b) Company Options.

As of the Effective Time, all Company Options shall no longer be outstanding and shall automatically terminate and cease to exist, and each holder of a Company Option shall cease to have any rights with respect thereto, except the right to receive the Option Cash Payment, if any.

(c) Company Restricted Stock. As of the Effective Time each share of Company Restricted Stock that is outstanding immediately prior to the Effective Time shall become fully vested and all restrictions thereon shall lapse (except that such Company Restricted Stock that is earned based on the achievement of performance goals (as opposed to based on the passage of time) (the "Performance-Based Company Restricted Stock") shall instead become earned and vested in accordance with the terms of the applicable award agreements) and shall be cancelled and terminated, by virtue of the Merger and without any action on the part of the holder of any share of Company Restricted Stock, and converted into the right at the Effective Time to receive, a cash payment with respect thereto equal to the product of (i) the total number of shares of Company Restricted Stock outstanding immediately prior to the Effective Time and (ii) the Merger Consideration, less any required withholding Taxes in accordance with Section 3.2(h) (the "Restricted Stock Payment"), payable pursuant to Section 3.5(e) (except that with respect to such Performance-Based Company Restricted Stock, unless the Company and the holder thereof otherwise agree, the Restricted Stock Payment in respect thereof shall instead become payable in accordance with the terms and conditions of the applicable award agreements), subject, however, to any rights of such holder pursuant to Section 3.3. As of the Effective Time, all shares of Company Restricted Stock (including the Performance-Based Company Restricted Stock) shall no longer be outstanding and shall automatically terminate and cease to exist, and each holder of

shares of Company Restricted Stock shall cease to have any rights with respect thereto, except the right to receive the Restricted Stock Payment pursuant to this Section 3.5(c).

(a) A complete list of each Company Benefit Plan is identified in Section 4.10(a) of the Company Disclosure Letter.

(b) Save in respect of the UK DB Plans, neither the Company nor any Company Subsidiary is or has at any time in the last six years been the employer or connected or associated with the employer (as those terms are used in the UK Pensions Act 2004) of a UK defined benefit pension plan.

(c) The Liabilities (actual and contingent) of the Company, the Company Subsidiaries and the Magnox Companies in respect of the UK Magnox Plans are indemnified by a Governmental Entity, and in the event that the Magnox Parent Body Agreement is terminated, none of the Company or any of the Company Subsidiaries will have any Liability (actual or contingent) in respect of the UK Magnox Plans at that time and the new provider and successful bidder and the Magnox Companies will be responsible for any such Liability. No contribution notice or financial support direction has been issued (or has been threatened to be issued) by the UK Pensions

Regulator against the Company or any Company Subsidiary in relation to any of the UK DB Plans and, to the Company's Knowledge, no circumstances exist or have existed at any time which could give rise to the issue of such a contribution notice or financial support direction. None of the principal employer, the trustees or the UK Pensions Regulator have notified the Company or any Company Subsidiary that it/they intend to wind up any of the UK DB Plans in whole or in part without the consent of the Company or the relevant Company Subsidiary and, to the Company's Knowledge, no act, event or omission has occurred which may lead to the winding up of any of the UK DB Plans.

(d) Each Company Benefit Plan has been operated and administered in all material respects in accordance with its terms and applicable Law, including, but not limited to, ERISA and the Code. There are no pending, or to the Company's Knowledge, threatened investigations by any Governmental Entity, termination proceedings, legal actions or other claims (except routine claims for benefits payable under the Company Benefit Plans) against or involving any Company Benefit Plan, the assets of any of the trusts under such Company Benefit Plans or the sponsor or administrator of any of the Company Benefit Plans, or against any fiduciary of the Company Benefit Plans, or asserting any rights to or claims for benefits under any Company Benefit Plan, other than any such investigations, proceedings, legal actions or claims that would give rise to any material Liability of the Company, and, to the Company's Knowledge, there are no facts that could give rise to any material Liability of the Company in the event of any such action.

(e) Except as set forth in Section 4.10(e) of the Company Disclosure Letter, (i) no Company Benefit Plan is a Multiemployer Plan, a "multiple employer plan" (within the meaning of ERISA and the Code), or other pension plan subject to Section 302 or Title IV of ERISA or Section 412 of the Code, and (ii) none of the Company or the Company Subsidiaries or any ERISA Affiliate sponsors, maintains, contributes to or has an obligation (contingent or otherwise) to contribute to, or has sponsored, maintained, contributed to or had an obligation (contingent or otherwise) to contribute to a Multiemployer Plan, multiple employer plan or other pension plan subject to Section 302 or Title IV of ERISA or Section 412 of the Code. No Liability under Title IV or Section 302 of ERISA has been incurred by the Company or any ERISA Affiliate that has not been satisfied in full, and no condition exists that presents a material risk to the Company or any Company Subsidiary or any ERISA Affiliate of incurring any such Liability, including, without limitation, any Liability to a Multiemployer Plan as a result of a complete or partial withdrawal therefrom. Except as stated in the immediately preceding sentence, neither the Company nor any Company Subsidiary would reasonably be expected to incur any Liability to a Multiemployer Plan in the event of a complete withdrawal therefrom on the Closing Date.

(f) Where the Code is applicable, each Company Benefit Plan (excluding the UK DB Plans) intended to be qualified under Section 401(a) of the Code, and the trust (if any) forming a part thereof, has received a favorable determination or opinion letter from the IRS as to its qualification under the Code and to the effect that each such trust is exempt from taxation under Section 501(a) of the Code. In respect of each Company Benefit Plan that is otherwise intended to be tax qualified, the relevant Governmental Entity has confirmed this tax status. In the case of all Company Benefit Plans covered by this section, to the Knowledge of the Company, nothing has occurred since the date of such determination, opinion letter or registration that would reasonably be expected to adversely affect such qualification or tax-exempt status.

(g) No prohibited transaction (as described in Section 406 of ERISA or Section 4975 of the Code, other than a transaction that is exempt under a statutory or administrative exemption) has occurred with respect to any Company Benefit Plan which would reasonably be expected to result in any material Liability to the Company. To the Company's Knowledge, neither the Company nor any Company Subsidiary nor any other fiduciary for which the Company or any Company Subsidiary has any indemnity obligation has any material Liability for breach of fiduciary duty

where one exists or any other failure to act or comply in contravention to a contractual or legislative duty in connection with the administration or investment of the assets of any Company Benefit Plan.

(h) All contributions (including all employer contributions and employee salary reduction contributions) required to have been made under any of the Company Benefit Plans as of the date of this Agreement have been made in all material respects by the due date thereof (including any valid extension), or, if not yet due, have been properly reflected on the most recent consolidated balance sheet filed or incorporated by reference in the Company Financial Statements.

(i) None of the Company Benefit Plans provide for post-employment life or health insurance, or other welfare benefits coverage for any current or former employees or beneficiaries or dependents thereof, except as may be required under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended ("COBRA") or other applicable Law. Each of the Company, any Company Subsidiary and any ERISA Affiliate which maintains a "group health plan" within the meaning of Section 5000(b)(1) of the Code has complied in all material respects with the notice and continuation requirements of Section 4980B of the Code, COBRA, Part 6 of Subtitle B of Title I of ERISA.

(j) Neither the Company nor any Company Subsidiary has a Contract, plan or commitment to create any additional Company Benefit Plan or to modify any existing Company Benefit Plan, except to the extent required by applicable Law. No employee of the Company or any Company Subsidiary has a contractual right to a defined benefit pension benefit in respect of service following the Effective Time.

(k) Each of the Company and the Company Subsidiaries have withheld and paid all amounts required by Law or by agreement to be withheld from the wages, salaries, and other payments to employees, officers, director or consultants thereof, and are not liable for any arrears of wages or any Taxes or any penalty for failure to withhold or pay such amounts, except for any failure which would not be reasonably expected to result in material Liability to the Company.

(l) Except as set forth in Section 4.10(l) of the Company Disclosure Letter, neither the execution and delivery of this Agreement nor the consummation of the Merger or any of the other transactions contemplated hereby (either alone or in conjunction with any other event) will, except as expressly contemplated by this Agreement, (i) entitle any current or former employee, officer, director or consultant of the Company or any Company Subsidiary to enhanced severance or termination pay, change in control or similar payments or benefits, (ii) result in, cause the accelerated vesting or delivery of, or increase the amount or value of, any payment or benefit to any such employee, officer, director or consultant, (iii) trigger any payment or funding (through a grantor trust or otherwise) of any compensation or benefits under, increase the amount payable or trigger any other material obligation pursuant to, or increase the cost of, any Company Benefit Plan or (iv) result in any breach or violation of, or a default under, any Company Benefit Plan.

(m) Other than payments or benefits that may be made to the persons listed in Section 4.10(m) of the Company Disclosure Letter, no amount that could be received (whether in cash or property or the vesting of property) as a result of any of the Merger or any of the other transactions contemplated hereby (alone or in combination with any other event) by any current or former employee, officer, director or consultant of the Company or any Company Subsidiary who is a "disqualified individual" (as such term is defined in Treasury Regulation Section 1.280G-1) under any Company Benefit Plan or other compensation arrangement could be characterized as an "excess parachute payment" (as such term is defined in Section 280G(b)(1) of the Code).

(n) Each Company Benefit Plan has been maintained and operated in documentary and operational compliance with Section 409A of the Code or an available exemption therefrom. All

Company Options have been granted at per share exercise price that is at least equal to the fair market value of a share of the underlying Company Common Stock as of the date the Company Option was granted, as determined in accordance with applicable Law, including Section 409A of the Code.

(o) The assets of each Company Benefit Plan are sufficient to satisfy its Liabilities (current and contingent), or the benefits provided by the Company Benefit Plan are fully insured.

Section 5.6 Financing.

(a) Parent has delivered to the Company (i) true and complete copies of (A) the executed commitment letters from the Debt Financing Sources (collectively, the "Debt Commitment Letters"), together with all schedules and exhibits thereto, pursuant to which the Debt Financing Sources party thereto have committed, subject to the terms and conditions set forth therein, to lend the amounts set forth therein to Parent (or its applicable subsidiary) for the purpose of financing the transactions contemplated by this Agreement (the "Debt Financing"), and (B) the executed equity commitment letter, dated as of the date hereof (the "Equity Commitment Letter" and, together with the Debt Commitment Letters, the "Financing Commitments") from the Guarantor and the other parties thereto pursuant to which the Guarantor has committed, subject to the terms and conditions set forth therein, to invest the amounts set forth therein for the purpose of financing the transactions contemplated by this Agreement (the "Equity Financing" and, together with the Debt Financing, the "Financing"), and (ii) copies of the executed fee letters and engagement letters (if any) from the Debt Financing Sources, with fee amounts and percentages and certain other terms (excluding any conditions) that would not affect the availability or in the aggregate materially and adversely affect the amount (other than in respect of upfront fees) of the Debt Financing redacted.

The Company shall cause the Proxy Statement to be mailed to the holders of Company Common Stock as of the record date established for the Company Stockholders Meeting as promptly as reasonably practicable after the date on which the SEC (or the staff of the SEC) confirms that it has no further comments on the Proxy Statement; provided, however, that the Company shall not (but may with the mutual consent of the Parties) mail the Proxy Statement prior to the Solicitation Period End Date. If at any time prior to the Effective Time, any event or circumstance relating to the Company or Parent or any of the Company's or Parent's Subsidiaries, or their respective officers or directors, should be discovered by the Company or Parent, respectively, which, pursuant to the Exchange Act, should be set forth in an amendment or a supplement to the Proxy Statement, such Party shall promptly inform the others.

Subject to and without limiting the rights of the Company Board to effect a Company Adverse Recommendation Change pursuant to Section 6.4(e), (i) the Company Board shall make the Company Recommendation at the Company Stockholders Meeting, (ii) such Company Recommendation shall be included in the Proxy Statement and (iii) the Company shall use its reasonable best efforts to solicit proxies in favor of the adoption of this Agreement and to obtain the Stockholder Approval.

(e) If on the date for which the Company Stockholders Meeting is scheduled (the "Original Date"), the Company has not received proxies representing a sufficient number of shares of Company Common Stock to approve the transactions contemplated hereby, whether or not a quorum is present, Parent shall have the right to require the Company, and the Company shall have the right, to postpone or adjourn the Company Stockholders Meeting to a date which shall not be more than forty-five (45) days after the Original Date. If the Company continues not to receive proxies representing a sufficient number of shares of Company Common Stock to approve the transactions contemplated hereby, whether or not a quorum is present, Parent shall have the right to require the Company to, and the Company may, make one or more successive postponements or adjournments of the Company Stockholders Meeting as long as the date of the Company Stockholders Meeting is not postponed or adjourned more than an aggregate of forty-five (45) days from the Original Date in reliance on this subsection. In the event that the Company Stockholders Meeting is adjourned or postponed as a result of applicable Law, including the need to supplement the Proxy Statement, any days resulting from such adjournment or postponement shall not be included for purposes of the calculations of numbers of days pursuant to this Section 6.2(e).

(b) Confidentiality and Restrictions.

Notwithstanding the commencement of the obligations of the Company under this Section 6.4(b), from and after the Solicitation Period End Date, the Company may, until 11:59 p.m. (New York City time) on the tenth (10^th) day following the Solicitation Period End Date (the "Cut-Off Date"), continue to engage in the activities described in clauses (i) through (iii) of this Section 6.4(b) with respect to an Acquisition Proposal submitted by an Exempted Person on or before the Solicitation Period End Date (and not subsequently withdrawn), including with respect to any amended or revised proposal submitted by such Exempted Person on or before the Cut-Off Date (but not a withdrawn Acquisition Proposal); provided, however, that, only in the case of clause (iii) above, the obligations in Section 6.4(d) , Section 6.4(e) and Section 6.4(f) shall apply at all times to all Acquisition Proposals of any Exempted Person.

(c) Notwithstanding anything to the contrary contained in Section 6.4(b), at any time after the Solicitation Period End Date and prior to, but not after, the receipt of the Stockholder Approval, the Company or the Company Board, directly or indirectly through the Company Representatives, may, subject to compliance with this Section 6.4:

(i) provide non-public information or data concerning the Company or any Company Subsidiary to any Person making a bona fide written Acquisition Proposal (which Acquisition Proposal did not result from a material breach of this Section 6.4); provided, however, that prior to providing such information, the Company receives from the Person an executed Acceptable Confidentiality Agreement; or

(ii) engage or participate in any discussions or negotiations with such Person with respect to such bona fide written Acquisition Proposal;

provided, however, that prior to taking any action described in Section 6.4(c)(i) or Section 6.4(c)(ii) above, (A) the Company Board shall have determined in good faith, based on the information then available and after consultation with its financial advisor and outside legal counsel, that such Acquisition Proposal either constitutes a Superior Proposal or would reasonably be expected to lead to a Superior Proposal, (B) the Company Board shall have determined, after consultation with outside legal counsel, that it is necessary to take such actions in order to comply with the Company Board's fiduciary duties to the stockholders of the Company under applicable Law, (C) the Company or the Company Board shall have given Parent prior written notice of such determinations and (D) all such information or data has previously been provided to Parent or is provided to Parent prior to or concurrently with the time it is provided to such Person.

(d) Except as expressly provided by Section 6.4(e), at any time after the date hereof, neither the Company Board nor any committee thereof shall:

(i) (A) publicly withhold or withdraw (or qualify or modify in a manner adverse to Parent or Merger Sub), or publicly propose to withhold or withdraw (or qualify or modify in a manner adverse to Parent or Merger Sub), the Company Recommendation or otherwise publicly repudiate the adoption, approval, recommendation or declaration of advisability by the Company Board or any such committee thereof of this Agreement, the Merger or the other transactions contemplated hereby, (B) adopt, approve, publicly declare advisable or recommend or publicly propose to adopt, approve, declare advisable or recommend any Acquisition Proposal, (C) allow the Company Recommendation to be excluded from the Proxy Statement, (D) fail to reject (or, if requested by Parent, fail to publicly recommend against) any Acquisition Proposal within ten (10) Business Days after such Acquisition Proposal is publicly announced, or (E) if a tender or exchange offer relating to equity securities of the Company is commenced by a Person unaffiliated with Parent, fail to send to the Company's security holders pursuant to Rule 14e-2 promulgated under the Securities Act, within ten (10) Business Days after such tender or exchange offer is first published, a statement disclosing that the Company Board recommends rejection of such tender or exchange offer (any action described in clauses (A), (B), (C), (D) or (E), a "Company Adverse Recommendation Change"); or

(ii) adopt, approve, recommend or declare advisable, or propose to adopt, approve, recommend or declare advisable, or cause or permit the Company or any Company Subsidiary to execute or enter into an Alternative Acquisition Agreement.

(e) Notwithstanding anything to the contrary set forth in this Agreement, at any time prior to receipt of the Stockholder Approval, the Company Board shall be permitted (x) to terminate this Agreement to enter into an Alternative Acquisition Agreement with respect to a Superior Proposal, subject to compliance with Section 8.1(c)(iii) and Section 8.2 if and only if (A) the Company Board has received an Acquisition Proposal that, in the good faith determination of the Company Board, after consultation with its financial advisor and outside legal counsel, constitutes a Superior Proposal, after having complied with, and giving effect to all of the adjustments which may be offered by Parent and Merger Sub pursuant to this Section 6.4(e), and (B) the Company Board determines in good faith, after consultation with outside legal counsel, it is necessary to take such action in order to comply with the directors' fiduciary duties to the stockholders of the Company under applicable Law, or (y) to effect a Company Adverse Recommendation Change, if and only if (A) (1) the Company Board has received an Acquisition Proposal that, in the good faith determination of the Company Board, after consultation with its financial advisor and outside legal counsel, constitutes a Superior Proposal, after having complied with, and giving effect to all

of the adjustments which may be offered by Parent and Merger Sub pursuant to this Section 6.4(e) or (2) an Intervening Event occurs and is continuing, and (B) the Company Board determines in good faith, after consultation with outside legal counsel, it is necessary to take such action in order to comply with the directors' fiduciary duties to the stockholders of the Company under applicable Law; provided that prior to the Company Board's effecting any such termination or Company Adverse Recommendation Change:

(i) the Company shall provide a written notice to Parent and Merger Sub that the Company Board intends to take such action and describing (1) the facts underlying the Company Board's determination that an Intervening Event has occurred and the rationale and basis for such Company Adverse Recommendation Change; or (2) the terms and conditions of the Superior Proposal that is the basis of such action (including the identity of the party making the Superior Proposal and any financing commitments related thereto, which shall include any fee letters, which letters may be redacted to omit the numerical amounts provided therein, as applicable) (a "Change of Recommendation Notice");

(ii) during the five (5) Business Day period following Parent's and Merger Sub's receipt of the Change of Recommendation Notice, the Company shall, and shall cause the Company Representatives to, negotiate with Parent and Merger Sub in good faith (to the extent Parent and Merger Sub desire to negotiate) to make adjustments in the terms and conditions of this Agreement, the Financing Commitments and the Guarantee (1) so as to obviate the need for an Company Adverse Recommendation Change as a result of the Intervening Event or (2) with respect to a Superior Proposal, so that such Superior Proposal ceases to constitute a Superior Proposal, as applicable; and

(iii) following the end of the five (5) Business Day period described above in Section 6.4(e)(ii), the Company Board shall have determined in good faith, after consultation with its financial advisor and outside legal counsel and taking into account the Tender Offer, any receipt of the Loan Amendments, changes to this Agreement, the Financing Commitments and the Guarantee proposed in writing by Parent and Merger Sub in response to the Change of Recommendation Notice or otherwise, that (A) such Company Adverse Recommendation Change in light of such Intervening Event is necessary to comply with the Company Board's fiduciary duties to the stockholders of the Company under applicable Law or (B)(1) such Superior Proposal continues to constitute a Superior Proposal, and (2) after consultation with its outside legal counsel, that it is necessary to take such action in order to comply with the directors' fiduciary duties to the stockholders of the Company under applicable Law.

If (x) there is any material change in the circumstances of such Intervening Event or another Intervening Event occurs, or (y) any amendment to the financial terms or any other amendment of such Superior Proposal is made, the Company shall deliver a new Change of Recommendation Notice to Parent and Merger Sub, and the Company shall be required to comply again with the requirements of this Section 6.4(e); provided, however, that references to the five (5) Business Day period above shall be deemed to be references to a three (3) Business Day period.

(f) From and after the Solicitation Period End Date, the Company shall (i) as promptly as reasonably practicable (and in any event within twenty-four (24) hours), advise Parent and Merger Sub of receipt by the Company of any Acquisition Proposal or any request for information that would reasonably be expected to lead to any Acquisition Proposal, the terms and conditions of any such Acquisition Proposal or request (including the identity of the party making such Acquisition Proposal), and shall as promptly as reasonably practicable (and in any event within twenty-four (24) hours) advise Parent and Merger Sub of any amendments to any such Acquisition Proposal or request, (ii) keep Parent fully and promptly informed of the status and material details (including

any change to any term or condition thereof) of any such Acquisition Proposal or request, and (iii) provide to Parent promptly after receipt or delivery thereof copies of all material correspondence and other written material sent or provided to the Company or any Company Subsidiary or any Company Representative from any Person that describes any of the terms or conditions of any such Acquisition Proposal or request. Without limiting the generality of the foregoing, the Company shall promptly notify Parent if the Company determines to begin providing information to any Third Party related to an Acquisition Proposal or determines to begin discussions with a Third Party related to an Acquisition Proposal.

(g) Nothing contained in this Section 6.4 shall be deemed to prohibit the Company or the Company Board, directly or indirectly through the Company Representatives, from (i) taking and disclosing to its stockholders a position with respect to a tender offer or exchange offer contemplated by Rule 14d-9, Rule 14e-2(a) or Item 1012(a) of Regulation M-A under the Exchange Act or (ii) making any "stop-look-and-listen" communication or similar communication of the type contemplated by Rule 14d-9(f) under the Exchange Act, in each case if, in the good faith judgment of the Company Board, after consultation with outside legal counsel, failure to so disclose would violate applicable Law; provided, however, that all actions taken or agreed to be taken by the Company or the Company Board or any committee thereof shall comply with the provisions of this Section 6.4 (including the provisions related to a Company Adverse Recommendation Change).

(h) So long as this Agreement has not been terminated, no Company Adverse Recommendation Change shall change the approval of the Company Board for purposes of causing any Takeover Statute to be inapplicable to the transactions contemplated by this Agreement.

(i) Without limiting the foregoing, it is agreed that any violation of the restrictions set forth in this Section 6.4 by any Company Representative or Affiliate of the Company or any Company Subsidiary shall be deemed to be a breach of this Section 6.4 by the Company.

Section 6.5 Reasonable Best Efforts.

(a) Subject to Section 6.4, the Parties hereto shall cooperate with each other and use their respective reasonable best efforts to consummate and make effective the transactions contemplated hereby and to cause the conditions to the Merger set forth in ARTICLE VII to be satisfied, including (i) the obtaining of all necessary actions or non-actions, consents and approvals (including those specified below) from Governmental Entities or other persons necessary in connection with the consummation of the transactions contemplated by this Agreement, including the Merger, and the making of all necessary registrations and filings (including filings with Governmental Entities, if any) and the taking of all reasonable steps as may be necessary to obtain an approval from, or to avoid an action or proceeding by, any Governmental Entity or other persons necessary in connection with the consummation of the transactions contemplated by this Agreement, including the Merger, (ii) the defending of any lawsuits or other legal proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the transactions, including the Merger, to be performed or consummated by such Party in accordance with the terms of this Agreement, including seeking to have any stay or temporary restraining Order entered by any court or other Governmental Entity vacated or reversed, and (iii) the execution and delivery of any additional instruments necessary to consummate the Merger and any other transactions to be performed or consummated by such Party in accordance with the terms of this Agreement and to carry out fully the purposes of this Agreement.

(b) In furtherance and not in limitation of the foregoing in Section 6.5(a), each of the Parties hereto shall promptly (and in no event later than ten (10) Business Days following the date that this Agreement is executed) (i) make and not withdraw (except with the prior written consent of

the other Party) its respective filings under the HSR Act, and the Parties shall request early termination of the statutory waiting period with respect thereto, and (ii) make in good faith such joint filings with CFIUS as shall be appropriate pursuant to Exon-▇▇▇▇▇▇, with respect to the transactions contemplated hereby, including the Merger, and thereafter use their reasonable best efforts to make any other required submissions and substantially comply with any additional requests for information by any antitrust authority or CFIUS, and (iii) as promptly as reasonably practicable make all filings or notifications to any other foreign or multijurisdictional body that are required under any applicable Antitrust Laws, or that are otherwise agreed by the Parties to be advisable in connection with the completion of the Merger and the other transactions contemplated by this Agreement.

Further, and for the avoidance of doubt, Parent will take any and all actions necessary in order to ensure that (x) no requirement for any non-action by or consent or approval of the Antitrust Division of the Department of Justice, the Federal Trade Commission or other foreign or U.S. Governmental Entity with respect to any Antitrust Laws, (y) no decree, judgment, injunction, temporary restraining order or any other Order in any suit or proceeding with respect to any Antitrust Laws, and (z) no other matter relating to any Antitrust Laws would preclude consummation of the Merger by the End Date. Each Party will bear its own costs for the preparation and filing of any notification and report required by any Antitrust Law or response to any request for additional information.

(d) In furtherance and not in limitation of the foregoing in Section 6.5(a), as promptly as practicable after the date of this Agreement, and no later than five (5) Business Days after the date of this Agreement or such other period as may be agreed in writing by the Parties, the Company and Parent shall file with NRC an application requesting consent under Section 184 of the Atomic Energy Act and 10 C.F.R. § 50.80 for the indirect transfer of control of the NRC Licenses as a result of the Merger, and any other related approvals required under the NRC Consents required to be obtained with respect to the NRC Licenses. The Parties shall use, their reasonable best efforts to obtain such consents as promptly as practicable. Each Party will bear its own costs of the preparation of any such filings and NRC fees shall be equally shared by the Parties. Thereafter, the Company and Parent shall cooperate with one another to facilitate NRC review of the application by providing the NRC staff with such documents or information that the NRC staff may require any of the Parties to provide or generate. Notwithstanding anything to the

contrary contained in this Agreement, with respect to the NRC Consents required to be obtained with respect to the NRC Licenses, no Party nor any of their respective Affiliates shall agree to, or be required to agree to, any conditions, provisions, amendments, agreements, Liabilities, or terms to which any of paragraphs (i) through (iii) of Section 7.1(e) apply, taken individually or in the aggregate.

(e) In furtherance and not in limitation of the foregoing in Section 6.5(a), as promptly as practicable after the date of this Agreement, and no later than five (5) Business Days after the date of this Agreement or such other period as may be agreed in writing by the Parties, the Company shall cause ES EU to notify the NDA in writing of the Merger and to request the written consent of the NDA to the indirect change of control of ES EU consequent to the Merger as required by the Magnox Parent Body Agreement (the "NDA Consent"). The Company shall use, and shall cause ES EU to use, its reasonable best efforts to obtain the NDA Consent within sixty (60) days after the date of this Agreement. In furtherance and not in limitation of the following in Section 6.5(h), the Company shall promptly notify Parent upon the receipt by the Company or ES EU of any comments from the NDA (or the staff of the NDA) or any request of the NDA (or the staff of the NDA) with respect to the NDA Consent, and shall provide Parent with copies of all correspondence between the Company, ES EU and the Company Representatives, on the one hand, and the NDA (or the staff of the NDA), on the other hand. The Company shall use, and cause ES EU to use, its reasonable best efforts to respond as promptly as reasonably practicable to any comments of the NDA (or the staff of the NDA) with respect to the NDA Consent, and the Parties shall co-operate with one another to facilitate the NDA's review of the request for the NDA Consent by providing the NDA as promptly as reasonably practicable with such documents or information that the NDA may reasonably request or require any of the Parties or their respective Subsidiaries to provide. Notwithstanding anything to the contrary contained in this Agreement, with respect to the NDA Consent, no Party nor any of their respective Affiliates shall agree to, or be required to agree to, any conditions, provisions, amendments, agreements, Liabilities, or terms to which any of paragraphs (i) through (iii) of Section 7.1(e) apply, taken individually or in the aggregate.

(f) Each of Parent and the Company shall give (or shall cause its respective Subsidiaries (as well as, in the case of the Company, the Magnox Companies) to give) any notices to Third Parties, and Parent shall use, and cause each of its Affiliates to use, its reasonable best efforts, and the Company shall use its reasonable best efforts to cooperate with Parent in its efforts, and the Company shall use, and cause each of its Subsidiaries and the Magnox Companies to use, its reasonable best efforts to obtain any Third Party consents not covered by Section 6.5(a) through Section 6.5(e) above that are necessary, proper or advisable to consummate the Merger or to avoid the loss as the result of the Merger of any material Permit, Company Material Contract or Government Bid to which the Company or any Company Subsidiary or any Magnox Company is a party and for which an award has not been issued prior to the date of this Agreement. Each Party will bear its own costs incurred in connection with this Section 6.5(f). Notwithstanding anything to the contrary in this Agreement, in connection with obtaining any approval or consent from any Person (other than a Governmental Entity) with respect to the Merger, (i) without the prior written consent of Parent, none of the Company or any of its Subsidiaries or any of the Magnox Companies shall pay or commit to pay to such Person whose approval or consent is being solicited any cash or other consideration, make any commitment or incur any liability or other obligation due to such Person and (ii) neither Parent nor Merger Sub shall be required to pay or commit to pay to such Person whose approval or consent is being solicited any cash or other consideration, make any commitment or incur any liability or other obligation.

Section 6.6 Financing.

(a) Prior to the Closing, so long as the Loan Amendments are not in full force or effect, Parent shall use reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things that are necessary or advisable to:

(i) maintain in full force and effect the Financing Commitments in accordance with the terms and subject to the conditions thereof (subject to the approval right of the Company in clause (a)(v) below, and further, subject to clause (b) below); provided that Parent may (A) replace or amend the Debt Commitment Letters so long as such replacement or amendment would not adversely impact or delay in any material respect the ability of Parent to consummate the Merger or the Financing, and (B) amend (including pursuant to a joinder agreement or an amendment and restatement) the Debt Commitment Letters to add Debt Financing Sources that have not executed the Debt Commitment Letters as of the date hereof;

(ii) negotiate and enter into definitive agreements with respect to the Debt Financing on the terms and conditions contemplated by the Debt Commitment Letters (including any flex provisions related thereto), which agreements shall be in effect as promptly as practicable after the date hereof but in no event later than the Closing;

(iii) satisfy all conditions applicable to Parent or Merger Sub set forth in the Financing Commitments, including by consummating the Equity Financing pursuant to the terms of the Equity Commitment Letter;

(iv) consummate and obtain the Financing on the terms and conditions (including the flex provisions) set forth in the Financing Commitments, including using reasonable best

efforts to seek to enforce its rights under the Debt Commitment Letters in the event of a breach thereof by the Debt Financing Sources thereunder; and

(A) reduces the aggregate amount of the Financing from that contemplated in the Financing Commitments;

(B) imposes new or additional conditions, or otherwise expands, amends or modifies any of the conditions, to the receipt of the Financing, in each case in a manner adverse to Parent, Merger Sub and the Company (taken as a whole); or

(C) amends or modifies any other terms of the Financing Commitments in a manner that would adversely impact or delay in any material respect (x) the ability of Parent or Merger Sub to consummate the Merger and the other transactions contemplated by this Agreement or (y) the ability of Parent or Merger Sub to obtain the Financing in a timely manner.

As long as the Loan Amendments are not in full force or effect, Parent shall not release or consent to the termination of the obligations of the Debt Financing Sources, except for assignments and replacements of an individual lender under the terms of or in connection with the syndication of the Debt Commitment Letters or as otherwise contemplated by Section 6.6(a)(i) or Section 6.6(b). Any reference in this Agreement to (x) "Financing" shall include the financing contemplated by the Financing Commitments as amended or modified in compliance with this Section 6.6(a), and (y) "Financing Commitments," "Debt Commitment Letters" or "Equity Commitment Letter" shall include such documents as amended or modified in compliance with this Section 6.6(a).

(b) If the Loan Amendments are not in full force or effect and any portion of the Financing becomes unavailable on the terms and conditions (including the flex provisions) contemplated in the Financing Commitments, Parent shall promptly so notify the Company and shall, as promptly as practicable following the occurrence of such event, use reasonable best efforts to arrange and to obtain alternative financing commitments from alternative sources on terms not less favorable taken as a whole than those contained in the Financing Commitments to Parent and Merger Sub and in an amount sufficient to consummate the transactions contemplated by this Agreement, (the "Alternative Financing"), and to obtain a new financing commitment letter with respect to such Alternative Financing (an "Alternative Financing Commitment") which shall replace the existing Financing Commitments or such unavailable portion thereof. Parent shall promptly provide a true and complete copy of each Alternative Financing Commitment (and any fee letters or engagement letters redacted in a manner consistent with Section 5.6(a)) to the Company. In the event any Alternative Financing Commitment is obtained, any reference in this Agreement to (i) "Financing," "Debt Financing" or "Equity Financing" shall include the financing contemplated by the Financing Commitments as modified in compliance with this Section 6.6(b), and (ii) "Financing Commitments," "Debt Commitment Letters" or "Equity Commitment Letters" shall include the Financing Commitments that are not superseded by an Alternative Financing Commitment at the time in question and the Alternative Financing Commitments entered into in compliance with this Section 6.6(b) to the extent then in effect.

(c) Parent shall give the Company prompt (and in any event within five (5) Business Days) written notice: (i) of any default or breach by any party to any Financing Commitment of which Parent or Merger Sub becomes aware or any termination thereof; (ii) of the receipt of any written

notice or other communication from any party to a Financing Commitment regarding the existence of a material dispute or disagreement between or among any parties to any Financing Commitment that could reasonably cause a condition to the Financing Commitments not to be satisfied; and (iii) if for any reason Parent or Merger Sub has reasonably determined in good faith that it will not be able to obtain all or any portion of the Financing on the terms, in the manner or from the sources contemplated by the Financing Commitments (including the flex provisions).

(d) Each of Parent and Merger Sub acknowledges and agrees that neither the obtaining of the Loan Amendments, the Financing or any Alternative Financing, nor the completion of any issuance of securities contemplated by the Financing or any Alternative Financing, is a condition to the Closing and reaffirms its obligation to consummate the transactions contemplated by this Agreement irrespective and independently of the receipt of the Loan Amendments or the availability of the Financing or any Alternative Financing, or the completion of any such issuance, subject to the applicable conditions set forth in Section 7.1, Section 7.2 and Section 9.5.

In addition, the Company shall give prompt notice to Parent of any change or event having a Company Material Adverse Effect. Notwithstanding the above, the delivery of any notice pursuant to this Section 6.8 shall not cure any breach of any representation or warranty requiring disclosure of such matter prior to the date of this Agreement or otherwise limit or affect the remedies available hereunder to any Party.

Section 6.10 Employee Matters.

(a) During the one (1)-year period commencing at the Effective Time, Parent shall provide or shall cause the Surviving Corporation to provide to Continuing Employees a base salary or wage rate at least equal to the Continuing Employees' base salary or wage rate in effect as of immediately prior to the Effective Time and compensation and benefits that are, in the aggregate, no less favorable than the compensation and benefits being provided to Continuing Employees immediately prior to the Effective Time. Notwithstanding the foregoing, and subject always to any powers to amend, terminate or renegotiate a collective bargaining agreement, with respect to Continuing Employees whose terms and conditions of employment are governed by a collective bargaining agreement, Parent will honor such terms and conditions of employment and continue benefits as set forth therein.

(b) Without limiting paragraph (a) of this Section 6.10, (i) during the one (1)-year period commencing at the Effective Time, Parent shall provide, or shall cause the Surviving Corporation to provide, to Continuing Employees who experience a termination of employment severance benefits that are no less than the severance benefits that would have been provided under a Company Benefit Plan to such employees upon such a termination of employment immediately prior to the Effective Time.

(c) For purposes of eligibility, vesting, and determination of level of benefits (but not for purposes of benefit accruals under any defined benefit pension plan) under the compensation and benefit plans, programs, agreements and arrangements of Parent or its Affiliates, the Company, the Surviving Corporation or any respective Subsidiary and Affiliate thereof providing benefits to any Continuing Employees after the Closing (the "New Plans"), including for purposes of accrual of vacation and other paid time off and severance benefits under New Plans, each Continuing Employee shall be credited with his or her years of service with the Company, the Company Subsidiaries and their respective Affiliates (and any additional service with any predecessor employer) before the Closing, to the same extent as such Continuing Employee was entitled, before the Closing, to credit for such service under a corresponding Company Benefit Plan; provided, however, that no such service shall be recognized to the extent that it would result in a duplication of benefits. In addition and without limiting the generality of the foregoing: (i) each Continuing Employee shall be immediately eligible to participate, without any waiting time, in any and all New Plans to the extent coverage under such New Plan replaces coverage under a comparable Company Benefit Plan in which such Continuing Employee participated immediately before the replacement; and (ii) for purposes of each New Plan that constitutes a group health plan made available to any Continuing Employee after the Effective Time, Parent shall use reasonable best efforts to, or shall cause the Surviving Corporation to, cause all pre-existing condition exclusions and actively-at-work requirements of such New Plan to be waived for such Continuing Employee and his or her covered dependents to the extent such exclusions or requirements would have been waived or satisfied under the Company Benefit Plan in which such Continuing Employee participated immediately prior to the Effective Time, and cause any eligible expenses incurred by such Continuing Employee and his or her covered dependents under a Company Benefit Plan during the portion of the plan year that includes the Effective Time to be taken into account under such New Plan for purposes of satisfying all deductible, co-insurance, co-payment and maximum out-of-pocket requirements applicable to such Continuing Employee and his or her covered dependents for the applicable plan year to the extent such amounts would have been taken into account under the Company Benefit Plan in which such Continuing Employee participated immediately prior to the Effective Time.

(d) No provision of this Agreement shall (i) create any third-party beneficiary or other rights in any current or former employee, director or other service provider of the Company or any Company Subsidiary, including rights in respect of any benefits that may be provided, directly or indirectly, under any Company Benefit Plan or any New Plan or rights to continued employment or service with Parent or its Affiliates, the Company, the Surviving Corporation or any respective Subsidiary and Affiliate thereof, (ii) be construed as an amendment, waiver or creation of or limitation on the ability to terminate any Company Benefit Plan or any New Plan, or (iii) limit the ability of Parent or its Affiliates, the Company, the Surviving Corporation or any respective Subsidiary and Affiliate thereof to terminate the employment of any employee of the Company or any Company Subsidiary.

Section 6.12 Directors' and Officers' Indemnification and Insurance.

(a) For not less than six (6) years after the Effective Time, Parent and the Surviving Corporation shall (and Parent shall cause the Surviving Corporation to) (i) indemnify, defend and hold harmless, and advance expenses to, Indemnified Parties with respect to all acts or omissions by them in their capacities as such at any time prior to the Effective Time, to the fullest extent

required by: (x) the Company Certificate of Incorporation or the Company By-laws (or equivalent organizational or governing documents of any Company Subsidiary or Affiliate of the Company as in effect on the date of this Agreement) and (y) any indemnification agreement of the Company or any Company Subsidiary or other applicable contract as in effect on the date of this Agreement, and (ii) not amend, repeal or otherwise modify any such provisions referenced in subsections (i)(x) and (y) above in any manner that would adversely affect the rights thereunder of any Indemnified Parties.

(b) Prior to the Effective Time, the Company shall or, if the Company is unable to, Parent shall cause the Surviving Corporation as of the Effective Time to, obtain and fully pay the premium for the non-cancellable extension of the directors' and officers' liability coverage of the Company's existing directors' and officers' insurance policies and the Company's existing fiduciary liability insurance policies (collectively, the "D&O Insurance"), in each case for a claims reporting or discovery period of at least six (6) years from and after the Effective Time with respect to any claim related to any period of time at or prior to the Effective Time from an insurance carrier with the same or better credit rating as the Company's current insurance carrier with respect to D&O Insurance with terms, conditions, retentions and limits of liability that are no less favorable than the coverage provided under the Company's existing policies, for an aggregate amount not to exceed eighteen times the last annual premium paid prior to the date of this Agreement for the D&O Insurance. If the Company or the Surviving Corporation for any reason fails to obtain such "tail" insurance policies as of the Effective Time, (i) the Surviving Corporation shall continue to maintain in effect, for a period of at least six (6) years from and after the Effective Time, the D&O Insurance in place as of the date hereof with the Company's current insurance carrier or with an insurance carrier with the same or better credit rating as the Company's current insurance carrier with respect to D&O Insurance with terms, conditions, retentions and limits of liability that are no less favorable than the coverage provided under the Company's existing policies as of the date hereof, or (ii) Parent will provide, or cause the Surviving Corporation to provide, for a period of not less than six (6) years after the Effective Time, the Indemnified Parties who are insured under the Company's D&O Insurance with comparable D&O Insurance that provides coverage for events occurring at or prior to the Effective Time from an insurance carrier with the same or better credit rating as the Company's current insurance carrier, that is no less favorable than the existing policy of the Company or, if substantially equivalent insurance coverage is unavailable, the best available coverage; provided, however, that Parent and the Surviving Corporation shall not be required to pay an annual premium for any such insurance in excess of three hundred percent (300%) of the last annual premium paid prior to the date of this Agreement for the D&O Insurance.

(c) The Indemnified Parties to whom this Section 6.12 applies shall be third party beneficiaries of this Section 6.12. The provisions of this Section 6.12 are intended to be for the benefit of and shall be enforceable by each Indemnified Party and his or her successors, heirs or representatives. Parent shall pay all reasonable expenses, including attorneys' fees, that may be incurred by any Indemnified Party in enforcing the indemnity and other obligations provided in this Section 6.12.

(d) The rights of each Indemnified Party under this Section 6.12 shall be in addition to any rights such person may have under the certificate of incorporation or bylaws of the Company, the Surviving Corporation or any of Company Subsidiary, or under any applicable Law or under any agreement of any Indemnified Party with the Company or any Company Subsidiary.

(e) Notwithstanding anything contained in Section 9.1 or Section 9.7 to the contrary, this Section 6.12 shall survive the consummation of the Merger indefinitely and shall be binding, jointly and severally, on all successors and assigns of Parent, the Surviving Corporation and its Subsidiaries, and shall be enforceable by the Indemnified Parties and their successors, heirs or

representatives. In the event that Parent or the Surviving Corporation or any of its successors or assigns consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or transfers or conveys all or a majority of its properties and assets to any Person, then, and in each such case, proper provision shall be made so that the successors and assigns of Parent or the Surviving Corporation, as applicable, shall succeed to the obligations set forth in this Section 6.12.

Section 6.13 Section 16 Matters. Prior to the Effective Time, the Company shall take such further actions, if any, as may be necessary or appropriate to ensure that the dispositions of equity securities of the Company (including derivative securities) pursuant to the transactions contemplated by this Agreement by any officer or director of the Company who is subject to Section 16 of the Exchange Act are exempt under Rule 16b-3 promulgated under the Exchange Act.

(a) Representations and Warranties.

Section 7.4 Frustration of Closing Conditions. Neither the Company, on the one hand, nor Parent or Merger Sub, on the other hand, may rely on the failure of any condition set forth in ARTICLE VII to be satisfied if such failure was caused by the Company's failure or either Parent's or Merger Sub's failure, respectively, to act in good faith to comply with this Agreement and consummate the transactions provided for herein.

ARTICLE VIII
TERMINATION, AMENDMENT AND WAIVER

Section 8.1 Termination. Notwithstanding anything in this Agreement to the contrary, this Agreement may be terminated and the Merger abandoned at any time prior to the Effective Time, whether before or after the Stockholder Approval is obtained (except as otherwise expressly noted), only as follows:

(a) by mutual written consent of each of Parent and the Company;

(b) by either Parent or the Company:

(i) if the Merger shall not have been consummated by 11:59 p.m., New York City time, on October 7, 2013 (such date, as it may be extended as provided below, the "End Date"); provided, however, that (A) the End Date may be extended by Parent (by written notice thereof to the other Parties), from time to time, for an additional aggregate period of time not to exceed three (3) months if all other conditions to consummation of the Merger are satisfied or capable of then being satisfied and the sole reason that the Merger has not been consummated by the then-current End Date is that one or more conditions set forth in Section 7.1(b), Section 7.1(c) , Section 7.1(d), or Section 7.1(e), in each case relating to the NRC Consents or the NDA Consent, has not been satisfied, and (B) the right to terminate this Agreement pursuant to this Section 8.1(b)(i) shall not be available to any Party if the failure of such Party to perform any of its obligations under this Agreement, the failure to act

in good faith or the failure to use its reasonable best efforts to consummate the Merger and the other transactions contemplated by this Agreement has been a principal cause of or resulted in the failure of the Merger to be consummated on or before such date;

(ii) if any Order or other action of any Governmental Entity having competent jurisdiction is entered permanently enjoining, restraining or otherwise prohibiting the transactions contemplated by this Agreement, and such Order or other action has become final and nonappealable; provided, however, that the right to terminate this Agreement under this Section 8.1(b)(ii) shall not be available to a Party if the issuance of such final, non-appealable Order was primarily due to the failure of such Party, and in the case of Parent, including the failure of Merger Sub, to perform any of its obligations under this Agreement; or

(iii) if the Stockholder Approval is not obtained at the Company Stockholders Meeting or any adjournment or postponement thereof at which the Merger has been voted upon;

(i) if (A) there exists a breach of any representation or warranty of Parent or Merger Sub contained in this Agreement such that the closing condition set forth in Section 7.3(a) would not be satisfied or (B) Parent or Merger Sub shall have breached any of the covenants or agreements contained in this Agreement to be complied with by Parent or Merger Sub such that the closing condition set forth in Section 7.3(b) would not be satisfied, and, in the case of either (A) or (B), such breach is incapable of being cured on or before the End Date or is not cured by Parent within thirty (30) calendar days after Parent receives written notice of such breach from the Company; provided that the Company shall not have the right to terminate this Agreement pursuant to this Section 8.1(c)(i) if, at the time of such termination, there exists a breach of any representation, warranty, covenant or agreement of the Company contained in this Agreement that would result in the closing conditions set forth in Section 7.2(a) or Section 7.2(b), as applicable, not being satisfied;

(ii) if all of the conditions in Section 7.1 and Section 7.2 have been satisfied (other than those conditions, which by their nature are to be satisfied by actions taken at the Closing) and Parent and Merger Sub fail to consummate the transactions contemplated by this Agreement within two (2) Business Days after the date the Closing should have occurred pursuant to Section 2.2; provided, however, that during such period of two (2) Business Days following the date the Closing should have occurred pursuant to Section 2.2 and for twenty-four (24) hours thereafter, no Party shall be entitled to terminate this Agreement pursuant to Section 8.1(b)(i); or

(iii) if prior to obtaining the Stockholder Approval, (A) the Company Board has determined to enter into an Alternative Acquisition Agreement with respect to a Superior Proposal in accordance with Section 6.4(e) and (B) the Company has complied in all material respects with Section 6.4; provided, that prior to or concurrently with termination pursuant to this Section 8.1(c)(iii), the Company pays the Company Termination Fee to Energy Capital Partners Management II, LP or its designee in accordance with Section 8.2(b)(i).

(d) by Parent:

(i) if (A) there exists a breach of any representation or warranty of the Company contained in this Agreement such that the closing condition set forth in Section 7.2(a) would not be satisfied or (B) the Company shall have breached any of the covenants or agreements contained in this Agreement to be complied with by the Company such that the closing condition set forth in Section 7.2(b) would not be satisfied, and, in the case of either (A) or (B), such breach is incapable of being cured on or before the End Date or is not cured by the

Company within thirty (30) calendar days after the Company receives written notice of such breach from Parent or Merger Sub; provided that Parent shall not have the right to terminate this Agreement pursuant to this Section 8.1(d)(i) if, at the time of such termination, there exists a breach of any representation, warranty, covenant or agreement of Parent or Merger Sub contained in this Agreement that would result in the closing conditions set forth in Section 7.3(a) or Section 7.3(b) , as applicable, not being satisfied;

(ii) if (A) the Company Board or any committee thereof shall have effected a Company Adverse Recommendation Change, (B) the Company Board shall have failed to hold the Company Stockholders Meeting or to use reasonable best efforts to solicit proxies in favor of the adoption of this Agreement and to obtain the Stockholder Approval, and such failure shall have been a material breach of Section 6.2(d), or (C) the Company Board fails to reaffirm publicly the Company Recommendation to the Company's stockholders to vote in favor of the Merger within ten (10) days of Parent's written request for such reaffirmation (or if the End Date is less than ten (10) days from the receipt of such request from Parent, by the close of business on the penultimate Business Day preceding the End Date);

(iii) if the Company enters into an Alternative Acquisition Agreement; or

(iv) if the Company shall have materially breached any provision of Section 6.4.

Section 8.2 Effect of Termination; Termination Fee.

(a) Effect of Termination Generally. In the event that this Agreement is terminated and the Merger abandoned pursuant to Section 8.1, written notice thereof shall be given to the other Party or Parties, specifying the provisions hereof pursuant to which such termination is made and the basis therefor described in reasonable detail, and this Agreement shall forthwith become null and void and of no effect without liability on the part of any Party hereto (or any of its Representatives), and all rights and obligations of any Party hereto shall cease, except for the rights and obligations contained in the Confidentiality Agreement, the Guarantee and the provisions of Section 6.3(b), this Section 8.2(a), Section 8.2(b), Section 8.2(c), Section 8.2(d), ARTICLE I and ARTICLE IX, which shall survive any termination of this Agreement; provided, however, that if (i) such termination results from an Intentional Breach committed prior to such termination and (ii) all of the conditions to Closing contained in Section 7.1 and, in the case of a termination by the Company, Section 7.2 and, in the case of a termination by Parent, Section 7.3, have been satisfied (other than those conditions, which by their nature are to be satisfied by actions taken at the Closing), then (A) no such termination shall relieve the Party who committed such Intentional Breach of any liability for actual damages incurred by the other Parties in an amount not to exceed Seventy-Five Million Dollars ($75,000,000), which damages resulted from such Intentional Breach (such actual resulting capped damages are referred to herein as the "Capped Damages"), and (B) the other Parties shall be entitled to all remedies available at law or in equity to seek to recover damages in an amount not to exceed the Capped Damages; provided, further, that if the Company terminates this Agreement pursuant to Section 8.1(c)(ii) and the reason that Parent and Merger Sub failed to consummate the transactions contemplated by this Agreement is that the financing contemplated by the Debt Commitment Letters is not available (other than as a result of breach of this Agreement by Parent or Merger Sub), then the sole and exclusive remedy of the Company Group against the Parent Group shall be to receive payment of the Parent Termination Fee pursuant to Section 8.2(c)(i) and any related costs, expense and interest pursuant to Section 8.2(d).

(b) Company Termination Fee and Expenses.

(i) (A) In the event that this Agreement is terminated by the Company pursuant to Section 8.1(c)(iii), the Company shall pay the Company Termination Fee to Energy Capital

Partners Management II, LP or its designee prior to or concurrently with such termination, by wire transfer of same day funds to one or more accounts designated by Parent or its designee (or by check if Parent fails to designate an account), and (B) in the event that this Agreement is terminated by Parent pursuant to Section 8.1(d)(ii), Section 8.1(d)(iii) or Section 8.1(d)(iv), the Company shall pay the Company Termination Fee to Energy Capital Partners Management II, LP or its designee promptly, but in any event within one (1) Business Day after the date of such termination, by wire transfer of same day funds to one or more accounts designated by Parent or its designee (or by check if Parent fails to designate an account).

(ii) In the event that this Agreement is terminated (A) by either Parent or the Company pursuant to Section 8.1(b) or (B) by Parent pursuant to Section 8.1(d)(i) , and subject to the delivery by Parent of an invoice and reasonable documentation thereof, the Company shall reimburse all of Parent's Reimbursable Expenses to Energy Capital Partners Management II, LP or its designee promptly, but in any event within one (1) Business Day after the date of such termination, by wire transfer of same day funds to one or more accounts designated by Parent or its designee (or by check if Parent fails to designate an account); provided, that in the event the Company has paid or caused to be paid Parent's Reimbursable Expenses, and a Company Termination Fee is thereafter payable, the Company Termination Fee otherwise payable shall be reduced by the amount of such Parent's Reimbursable Expenses which are actually reimbursed.

(iii) In the event that (A) this Agreement is terminated by either Parent or the Company pursuant to Section 8.1(b)(i) or Section 8.1(b)(iii) or by Parent pursuant to Section 8.1(d)(i), (B) the Company receives or has received an Acquisition Proposal from a Third Party after the date hereof, which Acquisition Proposal is publicly disclosed either (I) in the case of a termination pursuant to Section 8.1(b)(i), before the End Date, (II) in the case of a termination pursuant to Section 8.1(b)(iii), before the Company Stockholders Meeting (or such later date as such meeting is postponed or adjourned), or (III) in the case of a termination pursuant to Section 8.1(d)(i), before such termination, and (C) within twelve (12) months of the termination of this Agreement, the Company enters into an Alternative Acquisition Agreement with respect to an Acquisition Proposal with any Person other than Parent or its Affiliates, then the Company shall pay the Company Termination Fee to Energy Capital Partners Management II, LP or its designee promptly, but in any event within one (1) Business Day following the date on which the Company enters into such Alternative Acquisition Agreement, by wire transfer of same day funds to one or more accounts designated by Parent or its designee; provided, however, that for purposes of this Section 8.2(b)(iii), the references to "ten percent (10%)" in the definition of Acquisition Proposal shall be deemed to be references to "fifty percent (50%)."

(iv) For the avoidance of doubt, in no event shall the Company be obligated to pay the Company Termination Fee on more than one occasion or to pay Parent's Reimbursable Expenses on more than one occasion.

(v) Notwithstanding anything to the contrary set forth in this Agreement, but subject to Section 9.5 either (but not both) (A) Parent and Merger Sub's right to seek to recover damages in an amount not to exceed the Capped Damages pursuant to Section 8.2(a) or (B) Energy Capital Partners Management II, LP's right to receive payment from the Company of the Parent's Reimbursable Expenses and/or Company Termination Fee pursuant to Section 8.2(b) shall constitute the sole and exclusive remedy of Parent and Merger Sub against the Company and the Company Subsidiaries and any of their respective former, current or future general or limited partners, stockholders, members, managers, directors, officers, employees agents, affiliates or assignees (collectively, the "Company Group") for all losses and

damages suffered as a result of the failure of the transactions contemplated by this Agreement to be consummated or for a breach or failure to perform hereunder or otherwise, and upon payment of either the Company Termination Fee or any Capped Damages which are awarded, the Company Group shall not have any further liability or obligation relating to or arising out of this Agreement or the transactions contemplated thereby (except that the Company shall also be obligated with respect to Section 8.2(d) and, in the event that Parent's Reimbursable Expenses are paid by the Company but not the Company Termination Fee, Section 8.2(b)(iii)).

(i) In the event that this Agreement is terminated by the Company pursuant to Section 8.1(c)(i) or Section 8.1(c)(ii), Parent shall pay or cause to be paid the Parent Termination Fee to the Company promptly, but in any event within two (2) Business Days following such termination, by wire transfer of same day funds to one or more accounts designated by the Company.

(ii) For the avoidance of doubt, in no event shall Parent and Guarantor be obligated to pay, or cause to be paid, the Parent Termination Fee on more than one occasion, whether pursuant to this Agreement or the Guarantee.

(iii) Notwithstanding anything to the contrary set forth in this Agreement, but subject to Section 8.2(a) and Section 9.5, the Company's right to receive payment from Parent of the Parent Termination Fee pursuant to Section 8.2(c)(i) shall constitute the sole and exclusive remedy of the Company and the Company Subsidiaries against Parent, Merger Sub, the Guarantor, the Debt Financing Sources or any of their respective former, current or future general or limited partners, stockholders, members, managers, directors, officers, employees, agents, Affiliates or assignees (excluding the Company, the Company Subsidiaries, the Magnox Companies and any Company Joint Ventures, collectively, the "Parent Group") for all losses and damages suffered as a result of the failure of the transactions contemplated by this Agreement to be consummated or for a breach or failure to perform hereunder or otherwise, and upon payment of the Parent Termination Fee, the Parent Group shall not have any further liability or obligation relating to or arising out of this Agreement or the transactions contemplated by this Agreement; provided, however, (A) that Parent shall also be obligated with respect to Section 8.2(d) and (B) if the proceeds of the Debt Financing are available to be drawn down at the Closing pursuant to the terms of the Debt Commitment Letters or if the failure of the proceeds of the Debt Financing to be available to be drawn down at the Closing pursuant to the terms of the Debt Commitment Letters is the result of a breach of this Agreement by Parent or Merger Sub, and all the conditions under Section 7.1 and Section 7.2 have been satisfied (other than those conditions that by their nature are to be satisfied at the Closing) and the Closing does not occur, then (x) Parent shall pay, or cause to be paid, to the Company an amount equal to the Parent Termination Fee not later than the second (2nd) Business Day after the Company terminates the Agreement; and (y) the Company shall be entitled to payment from Parent of an amount equal to the Company's aggregate losses, if any, in excess of the Parent Termination Fee resulting from Parent or Merger Sub's Intentional Breach of this Agreement (but, together with the receipt of the Parent Termination Fee, subject to the Capped Damages). In no event shall the Company be entitled to seek or obtain any recovery or judgment in excess of the Parent Termination Fee against the Debt Financing Sources, including for any type of damage relating to this Agreement; provided that nothing in this Agreement shall in any way limit or modify any Debt Financing Source's obligations to Parent or Merger Sub under the Debt Commitment Letters.

(iv) If any payment of the Parent Termination Fee is made pursuant to Section 8.2(c)(i), unless payments are owed pursuant to clause (y) of Section 8.2(c)(iii)(B), than such payment (A) shall constitute liquidated damages with respect to any claim for damages or any other claim which the Company would be entitled to assert against Parent, any member of the Parent Group (and such payment of the Parent Termination Fee shall be the sole and exclusive remedy) or any of their respective assets with respect to any such termination of this Agreement, and (B) shall constitute the sole and exclusive remedy with respect to any such termination of this Agreement based upon any breach or misrepresentation of any of the representations, warranties or covenants of Parent or Merger Sub in this Agreement, the failure to obtain Debt Financing or the failure by Parent to effect the Closing regardless of whether the Debt Financing is available. For the avoidance of doubt, Company is entitled to make a claim for both the Parent Termination Fee and for liabilities or damages arising from any breach or misrepresentation of any of the representations, warranties or covenants of Parent or Merger Sub in this Agreement, the failure to obtain Debt Financing or the failure by Parent to effect the Closing regardless of whether the Debt Financing is available.

(d) Acknowledgement. Each Party acknowledges that (i) the agreements contained in this Section 8.2 are an integral part of the transactions contemplated in this Agreement, (ii) the damages resulting from termination of this Agreement under circumstances where a Company Termination Fee, Parent's Reimbursable Expenses, or Parent Termination Fee are payable are uncertain and incapable of accurate calculation and therefore, the amounts payable pursuant to Section 8.2(b) or Section 8.2(c) are not a penalty but rather constitute liquidated damages in a reasonable amount that will compensate Parent or the Company, as the case may be, for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the transactions contemplated hereby, and (iii) without the agreements contained in this Section 8.2, the Parties would not have entered into this Agreement. Accordingly, if the Company or Parent, as the case may be, fails to timely pay any amount due pursuant to this Section 8.2 and, in order to obtain such payment, either Parent, Energy Capital Partners Management II, LP or the Company, as the case may be, commences a suit that results in a judgment against any Party for the payment of any amount set forth in this Section 8.2, such paying Party shall pay the prevailing Party's costs and expenses (including reasonable attorneys' fees) in connection with such suit, together with interest on such amount at the annual rate of five percent (5%) plus the prime rate as published in The Wall Street Journal in effect on the date such payment was required to be made through the date such payment was actually received, or such lesser rate as is the maximum permitted by applicable Law.

(e) Fees and Expenses. Subject to Section 6.5 and except as otherwise provided in this Section 8.2, all Expenses incurred in connection with this Agreement and the transactions contemplated by this Agreement shall be paid by the Party incurring such Expenses. If the Closing occurs, except as provided in Section 3.2(b), Parent shall pay, or cause to be paid, all documentary, sales, use, real property transfer, registration, value added, transfer, stamp, recording and similar Taxes, fees, and costs together with any interest thereon, penalties, fines, costs, fees, additions to tax or additional amounts with respect thereto incurred in connection with this Agreement and the transactions contemplated hereby, and shall file all Tax Returns related thereto, regardless of who may be liable therefor under applicable Law.

(f) In no event shall either Party be entitled to seek or obtain any recovery or judgment in excess of the Capped Damages which are awarded against the Party or any of their respective assets, and in no event shall either Party be entitled to seek or obtain any other damages of any kind against the other Party, including consequential, special, indirect or punitive damages for, or with respect to, this Agreement or the Guarantee or the transactions contemplated hereby and

thereby (including, any breach by either Party), the termination of this Agreement, the failure to consummate the transactions contemplated by this Agreement or any claims or actions under applicable Law arising out of any such breach, termination or failure; provided, however, this Section 8.2(f) shall not limit the right of the Parties to seek specific performance of this Agreement pursuant to, and subject to the limitations in, Section 9.5 prior to the termination of this Agreement; and provided, further, in no event will either Party be entitled to receive more than one of the following remedies: (i) a grant of specific performance as provided in Section 9.5, (ii) the payment of all or any portion of the Company Termination Fee, in the case of termination by the Parent, or the Parent Termination Fee, in the case of termination by the Company, under Section 8.2, and (iii) a recovery of damages in an amount not to exceed the Capped Damages.

Section 8.3 Extension; Waiver. At any time prior to the Effective Time, the Parties may, to the extent permitted by applicable Law and, subject to the proviso in Section 8.4, (a) extend the time for the performance of any of the obligations or other acts of the other Parties, (b) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto or (c) waive compliance with any of the agreements or conditions contained herein. Any agreement on the part of a Party to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such Party. Notwithstanding the foregoing, no failure or delay by the Company, Parent or Merger Sub in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise of any other right hereunder.

Section 8.4 Amendment. This Agreement may be amended by the Parties by action taken by or on behalf of their respective Boards of Directors at any time prior to the Effective Time; provided, that after approval of the Agreement by the stockholders of the Company, no amendment that, by Law or in accordance with the rules of any relevant stock exchange, requires further approval by such stockholders may be made without further stockholder approval. This Agreement may not be amended except by an instrument in writing signed by Parent and the Company. Notwithstanding anything to the contrary contained herein, Section 8.2(c)(iii), this Section 8.4, Section 9.5, Section 9.6 and Section 9.7 (and any provision of this Agreement to the extent a modification, waiver or termination of such provision would modify the substance of such Sections) may not be modified, waived or terminated in a manner that adversely affects the rights of the Debt Financing Sources without the prior written consent of the Debt Financing Sources.

ARTICLE IX
GENERAL PROVISIONS

The representations, warranties, covenants and agreements in this Agreement and any certificate delivered pursuant hereto by any Person shall terminate at the Effective Time or, except as provided in Section 8.2, upon the termination of this Agreement pursuant to Section 8.1, as the case may be, except that this Section 9.1 shall not limit any covenant or agreement of the Parties which by its terms contemplates performance after the Effective Time or after termination of this Agreement, including those contained in Section 6.10 and Section 6.12.

Section 9.3 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of Law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the fullest extent possible.

Section 9.4 Entire Agreement. This Agreement (together with the Exhibits, Parent Disclosure Letter, Company Disclosure Letter and the other documents delivered pursuant hereto), the Financing Commitments, the Guarantee and the Confidentiality Agreement constitute the entire agreement of the Parties and supersede all prior agreements and undertakings, both written and oral, between the Parties, or any of them, with respect to the subject matter hereof and thereof.

Section 9.5 Specific Performance.

(a) The Parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that the Parties hereto do not perform the provisions of this Agreement (including failing to take such actions as are required of it hereunder to consummate this Agreement) in accordance with its specified terms or otherwise breach such provisions. Accordingly, subject to the other provisions in this Section 9.5, the Parties acknowledge and agree that the Parties shall be entitled to an injunction, specific performance and other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof, in addition to any other remedy to which they are entitled at law or in equity. Subject to the other provisions in this Section 9.5, each of the Company and Parent acknowledges and agrees that, (i) each Party shall be entitled to seek to specifically enforce the terms and provisions of this Agreement, notwithstanding the potential availability of any monetary remedy set forth in Section 8.2, (ii) the provisions set forth in Section 8.2 (A) are not intended to, and do not adequately compensate for, the harm that would result from a breach of this Agreement and (B) shall not be construed to diminish or otherwise impair in any respect any Party's right to seek specific enforcement, but that upon the payment of either the Parent Termination Fee and, without duplication, if applicable, any Capped Damages which are awarded, such right to seek (or receive) specific enforcement shall be immediately terminated and extinguished, and (iii) the right of specific enforcement is an integral part of the transactions contemplated by this Agreement and without that right, neither the Company nor Parent would have entered into this Agreement.

(b) Notwithstanding the foregoing in Section 9.5(a), the right of the Company to obtain an injunction, or other appropriate form of specific performance or equitable relief, in each case, solely with respect to causing the Parent and the Merger Sub to, or to directly, cause the Equity Financing to be funded shall be subject to the requirements that: (A) all conditions in Sections 7.1 and 7.2 (other than those conditions that by their nature cannot be satisfied until the Closing Date, but each of which shall be capable of being satisfied on the Closing Date) have been satisfied, and remain satisfied, at the time when the Closing would have occurred but for the failure of the Equity Financing to be funded, and Parent and Merger Sub fail to complete the Closing by the date the Closing is required to have occurred pursuant to Section 2.2, (B) either (i) the Loan Amendments shall be in full force and effect, (ii) the Debt Financing or Alternative Financing has been funded, or (iii) the full proceeds of the Debt Financing or Alternative Financing would be available to be drawn down by the Parent at the Closing if the Equity Financing is funded at the Closing, and (C) the Company has irrevocably confirmed in writing that if specific performance is granted and the Equity Financing and the Debt Financing are funded, then it would take all actions that are within its control to cause the Closing pursuant to Section 2.2 to occur.

(c) Notwithstanding Section 9.5(a), the right of the Company to obtain an injunction, or other appropriate form of specific performance or equitable relief, in each case, solely with respect to causing Parent and Merger Sub to use reasonable best efforts to enforce the terms of the Debt Commitment Letters, which may include a demand that the Merger Sub and Parent file one or more lawsuits against the sources of Debt Financing to fully enforce such sources' obligations thereunder and the Parent's and the Merger Sub's rights thereunder, shall be subject to the requirements that: (A) all conditions in Sections 7.1 and 7.2 (other than those conditions that by their nature cannot be satisfied until the Closing Date, but each of which shall be capable of being satisfied on the Closing Date) have been satisfied, and remain satisfied, at the time when the Closing would have occurred but for the failure of the Debt Financing to be funded, and Parent and Merger Sub fail to complete the Closing by the date the Closing is required to have occurred pursuant to Section 2.2, (B) all conditions to the consummation of the Debt Financing contemplated by the Debt Commitment Letters (other than the receipt of the Equity Financing,

any conditions that are within the control of Parent or Merger Sub, and those conditions that by their nature cannot be satisfied until the Closing Date, but each of which shall be capable of being satisfied on the Closing Date) have been satisfied and remain satisfied, (C) the Loan Amendments shall not be in full force and effect and (D) the Company has irrevocably confirmed in writing that if specific performance is granted and the Equity Financing and the Debt Financing are funded, then it would take all actions that are within its control to cause the Closing pursuant to Section 2.2 to occur.

(d) Each of the Parties hereby further waives (i) any defense in any action for specific performance in accordance with this Section 9.5 that a remedy at law would be adequate or that an award of specific performance is not an appropriate remedy for any reason at law or in equity and (ii) any requirement under any Law to post security as a prerequisite to obtaining equitable relief.

(e) For the avoidance of doubt, while the Company may pursue (i) a grant of specific performance as provided in this Section 9.5, (ii) the payment of all or any portion of the Parent Termination Fee under Section 8.2(c), and/or (iii) a recovery of damages in an amount not to exceed the Capped Damages, under no circumstances shall the Company be permitted or entitled to receive more than one of the remedies described in clause (i), (ii) and (iii).

Section 9.6 GOVERNING LAW; JURISDICTION; WAIVER OF JURY TRIAL.

(a) This Agreement and all actions, proceedings or counterclaims (whether based on contract, tort or otherwise) arising out of or relating to this Agreement or the actions of Parent, Merger Sub or the Company in the negotiation, administration, performance and enforcement thereof, shall be governed by, and construed in accordance with the laws of the State of Delaware, without giving effect to any choice or conflict of laws provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Delaware. Notwithstanding anything herein to the contrary, the Parties hereto acknowledge and irrevocably agree that any claim, suit, controversy, dispute, action or proceeding, whether in law or in equity, whether in contract or in tort or otherwise, in which any Debt Financing Source is a party arising out of, or in any way relating to, the transactions contemplated hereby, including but not limited to any dispute arising out of or relating in any way to the Debt Financing, shall be governed by, and construed in accordance with, the laws of the State of New York.

(b) Each of Parent, Merger Sub and the Company hereby irrevocably submits to the exclusive jurisdiction of the Delaware Court of Chancery (or, if (but only if) the Delaware Court of Chancery shall be unavailable, any other court of the State of Delaware or any Federal court sitting in the State of Delaware) for the purpose of any action, proceeding or counterclaim (whether based on contract, tort or otherwise) arising out of or relating to this Agreement or the actions of Parent, Merger Sub or the Company in the negotiation, administration, performance and enforcement thereof, and each of the Parties hereto hereby irrevocably agrees that all claims in respect to such action or proceeding may be heard and determined exclusively in any Delaware state or federal court.

(c) Each of the Parties hereto (i) irrevocably consents to the service of the summons and complaint and any other process in any other action or proceeding relating to the transactions contemplated by this Agreement, on behalf of itself or its property, in the manner provided for in Section 9.2(a), (c) and (d), and nothing in this Section 9.6 shall affect the right of any Party to serve legal process in any other manner permitted by Law, (ii) consents to submit itself to the personal jurisdiction of the Delaware Court of Chancery (or, if (but only if) the Delaware Court of Chancery shall be unavailable, any other court of the State of Delaware or any Federal court sitting in the State of Delaware) in the event any dispute arises out of this Agreement or the transactions contemplated by this Agreement, (iii) agrees that it will not attempt to deny or defeat

such personal jurisdiction by motion or other request for leave from any such court and (iv) agrees that it will not bring any action relating to this Agreement or the transactions contemplated by this Agreement in any court other than the Delaware Court of Chancery (or, if (but only if) the Delaware Court of Chancery shall be unavailable, any other court of the State of Delaware or any Federal court sitting in the State of Delaware). Each of Parent, Merger Sub and the Company agrees that a final judgment in any action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law; provided, however, that nothing in the foregoing shall restrict any Party's rights to seek any post-judgment relief regarding, or appeal from, such final trial court judgment.

(d) Each of the Parties hereto (i) agrees that it will not bring or support any claim, suit, action, proceeding, cross-claim or third-party claim against the Debt Financing Sources in any way relating to this Agreement or any of the transactions contemplated by this Agreement, including any dispute arising out of or relating in any way to the Debt Financing or the performance thereof (each, a "Debt Financing Party Claim"), in any forum other than any state or federal court of competent jurisdiction sitting in the Borough of Manhattan, New York, New York, and any appellate court thereof, and each of the Parties hereto submits for itself and its property with respect to any such action to the exclusive jurisdiction of such courts, (ii) hereby waives, to the fullest extent permitted by law, any objection which any of them may have to the laying of venue of, and the defense of an inconvenient forum to the maintenance of, any such claim, suit, action or proceeding in any such court and (iii) the waiver contained in Section 9.6(e) shall apply to any Debt Financing Party Claim.

(e) EACH OF PARENT, MERGER SUB AND THE COMPANY HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE ACTIONS OF PARENT, MERGER SUB OR THE COMPANY IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT THEREOF. THE PARTIES HEREBY FURTHER WAIVE TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY ANY PARTY AGAINST ANY DEBT FINANCING SOURCE PARTIES IN ANY MATTER WHATSOEVER ARISING OUT OF OR IN RELATION TO OR IN CONNECTION WITH THIS AGREEMENT OR THE DEBT FINANCING OR THE PERFORMANCE THEREOF.

Section 9.7 No Third-Party Beneficiaries.

such Debt Financing Source without its prior written consent). The representations and warranties in this Agreement are the product of negotiations among the Parties hereto and are for the sole benefit of the Parties hereto. Any inaccuracies in such representations and warranties are subject to waiver by the Parties hereto in accordance with Section 8.3 without notice or liability to any other Person. The representations and warranties in this Agreement may represent an allocation among the Parties hereto of risks associated with particular matters regardless of the Knowledge of any of the Parties hereto. Accordingly, Persons other than the Parties hereto may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.

Section 9.8 Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the Parties (whether by operation of Law or otherwise) without the prior written consent of the other Parties; except that (a) Merger Sub may assign any of or all of its rights, interest and obligations under this Agreement to Parent or to any direct or indirect wholly-owned subsidiary of Parent and (b) Parent and Merger Sub may assign their respective rights, interest and obligations under this Agreement, in whole or in part, to any Debt Financing Source or other parties providing debt financing to the Surviving Corporation for purposes of creating a security interest herein or otherwise assigning as collateral in respect of any such debt financing, but no such assignment shall relieve the assigning party of its obligations hereunder. Subject to the foregoing, this Agreement will be binding upon, inure to the benefit of and be enforceable by the Parties and their respective successors and permitted assigns.

Section 9.9 Obligations of Parent and of the Company. Whenever this Agreement requires a Subsidiary of Parent to take any action, such requirement shall be deemed to include an undertaking on the part of Parent to cause such Subsidiary to take such action. Whenever this Agreement requires a Company Subsidiary to take any action, such requirement shall be deemed to include an undertaking on the part of the Company to cause such Company Subsidiary to take such action and, after the Effective Time, on the part of the Surviving Corporation to cause such Subsidiary to take such action.
